所以我的 Flutter 应用程序工作正常，但不幸的是，我的 USB 损坏了。所以我买了两个新的USB。但从那时起，每次运行我的项目时，我都会收到以下错误：

USB 没有物理损坏，并且在运行前确实显示了连接的设备。但是在运行visual studio代码和android studio后显示Lost connection。

我使用的是 Windows 10 和 Android 设备。我想在真实设备中测试和调试我的应用程序。有什么解决办法吗？

【问题讨论】：

这里可能会发生一些事情，但可以确定的是，您是否允许在手机上进行 USB 调试？ 【参考方案1】：

尝试创建一个新的默认 Flutter 项目并将其调试到您的手机中。

【讨论】：

【参考方案2】：

您是否尝试从手机/模拟器手动卸载并运行 flutter clean ，也尝试一次禁用 chrome 中 dart devtools 的自动打开

【讨论】：

【参考方案3】：

您可以通过 USB 进行简单的调试..否则您可以通过 LAN 连接您的设备..
